Some days ago on my Volvo 240 '93 lambda probe is always on.
Any ideas.

What do you mean? Is the lambda warning light illuminated, or is the
output of the O2 sensor high and not oscillating?

In my 240 the lambda light was on a timer that turned it on after a set
number of miles as a reminder to have the emissions system inspected.
Later US spec cars have onboard diagnostics that store fault codes, but
depending on where you are that might not be the case.
